    Hi everyone,

    My current configuration is:

    Athlon XP 1800+
    512 MB
    HD 80GB Hitachi
    Asus CD-RW
    Windows XP

    I changed the power supply for a new 350W one and it works fine, but I haven't been able to boot the system yet.
    If I connect everything up the only thing that will turn on is the fan of the processor and the power supply itself, but neither the HD or the CD-RW will.
    But if I disconnect the data cable from the motherboard both components will turn on.
    The HD is set as master and the CD-RW is slave, and they are plugged with the same data cable and same power chord.
    I tried another power supply and everything works fine, but using that one on that computer is not an option.
    I googled a couple of things like "change power supply" but none of them worked out.

    Thanks very much in advance

    Welcome

    The problem is only with the one PS? Things work fine when you replace it?

    The problem is with the new PS if the data cable is plugged to the motherboard(HD and CD-RW don't turn on). If I disconnect the data cable from the motherboard, Hd and CD-RW will power up. I took this new PS to the computer store where I bought it to have it tested and it worked fine.
